Prevalence of the glaucomas in Nepal.

I read the article titled “ Profile of the glaucomas and intervention in a large eye care center in South East Nepal” by Sarkar S et al (2010). The authors deserve special congratulations for presenting such a large hospital database. They have rightly pointed out that the hospital prevalence of primary angle closure glaucoma (PACG) is higher than that of the primary open angle glaucoma (POAG). The reason for this is the sudden-onset nature of the angle closure glaucoma associated with pain and visual impairment. A community survey of glaucoma would have shown the exact picture of the glaucoma prevalence.
